Page 14: Scpi Introduction
Common commands generally are not related to specific operation but to controlling overall instrument functions, such as reset, status, and synchroni- zation. All common commands consist of a three-letter mnemonic preceded by an asterisk: *RST *IDN? *SRE 8. Copyright © Itech Electronic Co., Ltd.
Page 15 In order to combine commands from different subsystems, you need to be able to reset the header path to a null string within a message. You do this by begin- ning the command with a colon (:), which discards any previous header path. Copyright © Itech Electronic Co., Ltd.
Page 16 Examples: :SYSTem:PRESet long-form :SYST:PRES short form :SYSTem:PRES long-form and short-form combination Note that each command word must be in long-form or short-form, and not something in between. Copyright © Itech Electronic Co., Ltd.
Page 17: Message Type Of Scpi
The simplest SCPI command is a single message unit consisting of a command header (or keyword) followed by a message terminator. The message unit may include a parameter after the header. The parameter can be numeric or a string. Copyright © Itech Electronic Co., Ltd.
Page 18 Command execution rules • Commands execute in the order that they are presented in the program message. • An invalid command generates an error and, of course, is not executed. Copyright © Itech Electronic Co., Ltd.
Page 19: Response Data Type
(;). Items within the same query are separated by commas (,). The following example shows the response message for a program message that contains four single item query commands: 0; 1; 1; 0 Copyright © Itech Electronic Co., Ltd.
Page 20: Command Format
Vertical stripes (|) separate several parameter options with given command strings. For example, {VPP|VRMS|DBM} indicates that you may assign "APP", "VRMS" or "DBM" in the above commands. Vertical stripes are not sent along with command strings. Copyright © Itech Electronic Co., Ltd.
Page 21 TRIG:COUNT 10 Question mark (?) You can insert question marks into a command to query current values of most Parameter. For example, the following commands will trigger to set the count as TRIG:COUN 10 Copyright © Itech Electronic Co., Ltd.
Page 22 (such as "DISP?;DISP:TEXT?"), <NL> will terminate response returned after response to the last query. In all cases, the program must read <NL> in response before another command is sent to the instrument, otherwise errors will be caused. Copyright © Itech Electronic Co., Ltd.
Page 23: Data Type
"OFF" or "0". In case of true conditions, the instrument will accept "ON" or "1". In query of Boolean settings, the in- strument will always return "0" or "1". Boolean parameter are required by the following commands: Copyright © Itech Electronic Co., Ltd.
Page 24: Remote Interface Connections
If the user want to change the settings of the instrument, for instance, the in- put setting value, the command SYST:REM must be sent to the instrument after finishing the connection between the instrument and PC. Copyright © Itech Electronic Co., Ltd.
